Abstract
The utility model discloses an electric heater, which comprises a shell, a fan and a radiator. The inside of the shell is divided into an upper cavity and a lower cavity, a semiconductor cooling piece is arranged in the upper cavity and the lower cavity of the shell and completely separates the upper cavity from the lower cavity, and the fan is arranged on the shell with the upper cavity and the lower cavity. The utility model has the advantages of simple structure, no need for any refrigerant during heat transfer, continuous operation, integrated cooling and heating, short heating and cooling time and capability of providing warm air for vehicles no matter whether the engine can provide heat.
Description
Technical field
The utility model belongs to automobile-used temperature-adjusting device technical field, especially relates to a kind of automobile-used electric heater.
Background technology
At present, existing automobile-used temperature-adjusting device is the cooling fluid exchange heating system by engine, the operation principle of engine warm braw is: when ECT is higher, cooling fluid flows through the heat exchanger in the warm air system, air and engine cold liquid that air blast is sent here carry out heat exchange, are sent in the car by each air outlet by air blast after the air heat.This system and device is simple and heat supply is reliable, do not need fuel in addition, as long as engine operation, just can produce hot water, but its significant disadvantages is also arranged, promptly must when ECT rises to systemic circulation, could heat, existing automobile-used temperature-adjusting device of while, use refrigerating function, must open air-conditioning system, need to consume a large amount of energy.
Summary of the invention
No matter provide a kind of simple in structure, hot transmission to heat one, heat whether cooling time is short has engine to provide thermal source that the electric heater of warm braw can be provided for vehicle without any need for cold-producing medium continuous operation, refrigeration but the purpose of this utility model is to improve the deficiency of prior art.
The purpose of this utility model is to realize like this, a kind of electric heater, form by housing, fan and radiator, be characterized in that enclosure interior is divided into upper and lower two cavitys, semiconductor chilling plate is installed between interior upper and lower two cavitys of housing and upper and lower two cavitys is isolated fully, and the housing of upper and lower two cavitys is provided with fan.
In order further to realize the purpose of this utility model, can be between semiconductor chilling plate and housing, to be provided with the insulation division board.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is that enclosure interior is divided into, following two cavitys, semiconductor chilling plate be installed in the housing on, between following two cavitys and make, following two cavitys are isolated fully, on, the housing of following two cavitys is provided with fan, convert electrical energy into heat or refrigeration by semiconductor chilling plate, be electric current transducing matrix part, when heat is transmitted without any need for cold-producing medium, but continuous operation, can freeze, can heat again, though refrigerating efficiency is general, but heating efficiency is very high, control by input current, can realize high-precision temperature control, add temperature detection and control device, be convenient to form automatic control system, thermal inertia is very little, heat, cooling time is very fast, under the situation of the good cold junction zero load of hot-side heat dissipation, energising was less than one minute, cooling piece just can reach maximum temperature difference, and temperature range can be realized for 130 ℃ to negative temperature from 90 ℃ of positive temperature, by fan heat or cold air be sent in the driver's cabin, the utility model electricity heater high efficient and reliable, cooling assembly is a solid state device, movement-less part, so crash rate is low, life-span was greater than 200,000 hours, noiseless during work, different with mechanical refrigeration system, do not produce noise during work.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
The specific embodiment
Embodiment 1, a kind of electric heater, with reference to Fig. 1, be that housing 4 inside are divided into upper and lower two cavitys, semiconductor chilling plate 3 is installed between upper and lower two cavitys in the housing 4 and upper and lower two cavitys is isolated fully, forms two independently spaces, and the both side surface of semiconductor chilling plate 3 is fixed with radiator 2, the housing 4 of upper and lower two cavitys is provided with fan 1, and this constitutes a kind of structure of the present utility model.
Embodiment 2, and a kind of electric heater with reference to Fig. 2, is on the basis of embodiment 1, are provided with insulation division board 5 at semiconductor chilling plate 3 and 4 of housings, and other and embodiment 1 are identical.
Claims (2)
1. electric heater, form by housing (4), fan (1) and radiator (2), it is characterized in that housing (4) inside is divided into upper and lower two cavitys, semiconductor chilling plate (3) is installed between interior upper and lower two cavitys of housing (4) and upper and lower two cavitys is isolated fully, and the housing of upper and lower two cavitys (4) is provided with fan (1).
